If a facility changes owners, but the manufacturing operations have not changed, are they REQUIRED to update their RMP?

Yes. If the owner of a facility changes, the RMP on record with EPA should reflect the current owner by the date ownership changes or responsibility for operation of the facility is transferred. You do not have to update each section of your RMP if the only thing that has changed is the name of the owner. All updates or corrections to your RMP must include the 12-digit EPA Facility Identification number (usually beginning with 1000) that was assigned to your facility. The EPA Facility ID was given to you in the notification letter you received from the RMP Reporting Center regarding the submission status of your RMP. For details on how to submit corrections, see the Web page for RMP*eSubmit.
